I think people who care about superintelligent AI risk don't believe an AI that is subservient to humans is the solution to AI alignment, for exactly the same reasons as you. Stuff like Coherent Extrapolated Volition* (see the paper with this name) which focuses on what all mankind would want if they know more and they were smarter (or something like that) would be a way to go.

*But Yudkowsky ditched CEV years ago, for reasons I don't understand (but I admit I haven't put in the effort to understand).
